How does it partially work?
What does the replacement result look like to be partial?
(By any chance, do the summary lines include "... by "? I think I account for those, but I don't recall.)
Also, note that my Teams chat, appearance setting is set to compact - meaning one person's post below the other's post, including my own posts. (Not comfy where my posts would appear to the right.)
Now perhaps the find/replace strings can be modified to work with comfy, but I never tried.
Note, if you modify your original post, please separate (post below) what is already there, otherwise it's too hard to compare, as there is no prior post to compare to.
